or
On the Drill and Blast menu, point to Edit, and then click Double Stitching.
Select a blast from the screen. Once selected, the following is then displayed.
Select the specification that will be used to define the blast hole attributes for the new holes. The drop-down list contains all of the specifications found in your Drill and Blast specifications file (specifications.dab).
Click OK.
Select a start hole.
You will then need to confirm whether you want to track holes along rows/edges or select the holes individually. The Track holes along rows/edges option will allow you to automatically track along rows/edges of the blast. If you want to have more control over the hole selection, then we recommend that you use the Select holes individually option.
Cancel with the mouse to select another start hole. Cancel again when you are ready to insert the new holes. The new holes will be created halfway between the selected holes and will be placed in a new row following the last row in the existing blast.
